1. A method for verifying measured data from at least one sensor system of a motor vehicle, the measured data directly or indirectly describe values of physical quantities, the method comprising:receiving, from an inertial navigation system, a first measured value at a first time, the first measured value being a speed value, an acceleration value, or a yaw rate of the motor vehicle associated with the motor vehicle;
receiving, from a satellite navigation system, a second measured value at the first time, the satellite navigation system including a global positioning system (GPS) receiver;
receiving, from an odometry navigation system, a third measured value at the first time, the odometry navigation system includes a wheel speed sensor on each wheel of the motor vehicle and a steering angle sensor;
mutually comparing, at a fusion filter in communication with the inertial navigation system, the satellite navigation system, and the odometry navigation system, the first, second, and third measured values in pairs, the first, second, and third measured values describing an identical quantity;
updating, at the fusion filter, the speed value, the acceleration value, or the yaw rate of the motor vehicle based on comparing the first, second, and third measured values and
outputting, from an output module in communication with the fusion filter, the updated speed value, the updated acceleration value, or the updated yaw rate of the motor vehicle.
